Pasquier de Vaux, Pasquerius de Vallibus, originally from the environs of Evreux, was received as a canon at Nôtre Dame by letters of the King of England on February 3, 1426.

He was, much later (December 7, 1425), procureur of the Chapter of Nôtre Dame for its lands of Tourny near Rouen. A licentiate in law in 1426, under Guillaume de Conti, another of the Maid's judges, then getting his doctorate at the same time as Thomas Fiesvet, he became a master regent of that faculty in 1427.

In 1433 Pasquier de Vaux went to Caen to protest against the creation of that University. He was received as a canon at Rouen, was Bedford's secretary and chaplain, and was commissioned by Henry VI to go to Rome to obtain the promotion of Louis de Luxembourg to the archbishopric.

Pasquier represented him at the time of his reception at Rouen, a ceremony of a character more political than religious, at which Pierre Cauchon and the Abbots of Fécamp and Mont Saint Michel were present.

On September 23, 1435, Pasquier de Vaux was called to the See of Meaux as bishop, and in 1439 we find him as Bishop of Evreux, where he had been transferred by Eugene IV, the French having just captured Meaux.

When the French entered Evreux he had himself made Bishop of Lisieux, vacant then (1443) by the death of Pierre Cauchon. He was in effect so determined a partisan of the English that after the capture of Evreux by Robert Floques in 1441, be did not want to recognize Charles VII as lord and master. Eugene IV, who had already been of service to him, allowed him to exchange it for Lisieux, the choicest English see, with Coutances. But Charles VII then lost patience and took possession of all his property.

At Lisieux we find Pasquier de Vaux taking the title of councilor to the King of England and president of the Chamber of Accounts. On July 20, 1443, the Parlement of Paris put his confiscated possessions up for sale.

He was present at the installation of Raoul Roussel as Archbishop of Rouen. Pasquier de Vaux died on July 11, 1447, at the very moment of the entry of Charles VII into the city of Lisieux.

This rich and important man, strongly attached to the English government, lived at Rouen in a mansion near the Mint. He was vicar-general in spiritualibus et in temporalibus of Cardinal Louis de Luxembourg, as well as Henry's councilor, and played a considerable rôle in Normandy during the English domination.

Very diligent in attending the Trial, Pasquier de Vaux declared himself especially in agreement with the deliberations of the University of Paris.
